High-Load waterjet Pistons

Hi-Load Piston 94k


Our Hi-Load piston is designed with stabilizing wear bands and energizer rings that eliminate the rocking and tilting common with the competitors' ancient U-Cup design. This not only reduces wear on the hydraulic cylinder, but it also greatly increases the life of the HP seals and plunger. We have witnessed customers almost doubling their HP seal life by simply switching their piston to the Hi-Load Piston. The improved support of the piston helps guide the plunger centered through the HP Seal, reducing wear and improving life. The old style U-Cup design has been known to rock so severely that it will scratch and destroy hydraulic cylinders at an astonishing rate.
